MARIUS OTTO, OF PARlSpFRANOE.

ARRANGEMENT Fo TRE SUPPORT AND CQOLING OF s TATicAL oz omz ERs.

ELPECIFICATION forming part of Letters Patent ltd-733,674, dated July14, 1963.

To all whom, it may concern.-

Beitknown that I, MARIUS OTTO, doctor of science, of No. 5 Avenue duBois de Bologne, Paris, France, have invented a certain new and usefulImproved Arrangement for the Support and Cooling of Statical Ozonizers;and I do hereby declare the following to be a full, clear, and exactdescription of the in vention, such as will enable others skilled in theart to which it appertains to make and use the same.

Ozonizers formed of plates of glass have many serious disadvantages, oneof the most important of which is the overheating of the dielectric andthe rupture which results. To avoid this cause of trouble, a suggestionhas been made of circulatinga stream of water around the glass plates orplunging them into a mass of water. It has also been suggested that thearmatures which protect the dielec-' tric substances should consist ofhollow casings within which a cooling liquid is caused to circulate; butall these methods present great diificulties in the way of insulationand convenience of installation.

The arrangement for supporting and cooling statical ozonizers which isthe subject of the present application for a patent enables the problemto be solved in a manner both simple and practical.

The invention is represented in detail in the accompanying drawings, inwhich- Figure 1 is a diagrammatic representation of the apparatus. Figs.2, 3, and 4 repre-' sent, respectively, a side elevation, a frontelevation, and a plan of a practical form for the construction of theapparatus.

) A sheet of iron a, provided at its upper end with an air-chamber b andan exhaust-pipe c, is suspended between two plates of glass d, which areheld at a suitable distance by insulating-clamps made of glass. To theexterior surface of each of these two plates of glass is fixed'ametallic conducting-surface e, covered with a layer of felt f. The wholearrangement is firmly secured by screws to the metallic supports 9. Twoperforated metal tubes h and i allow of the felt layers f beingcontinuously sprinkled with water.

Application filed May 26, 1903. Serial No. 168,899. (No model.)

7 The two exterior electrodes are connected to earth at If. Only themetallic sheet a is insulated and is connected by means of the wire Zwith one of the poles of a transformer m at high tension, of which theother pole is led to earth. (r

When the apparatus is in working order, the electric sparks leap theinterval between the sheet a and the interior surface of the dielectricd. Air flowing in the direction indicated by the arrows intersects thesesparks.

In the form of construction represented by Figs. 2, 3, and 4 five staticozonizers are grouped on the same metallic base.

Each of the portions of the apparatus is constituted as has beendescribed above, and consists of avmetallic sheet a, suspended betweentwo dielectric substances (1. Only one of these portions is shown indetail. The other four are indicated by the ar'matures g, which inclosethem. The two dielectric substances d carry on their exterior surface aconducting-electrode e and a layer of felt f, which is sprinkledcontinuously by a stream of water. The external electrodes 6 are joinedto earth, and thus avoid any difficulty of insulating the stream ofwater.

A discharge-indicator '11,, having a movable shutter, completes theapparatus. The central electrode is insulated by a glass tube It.

It is advisable to complete the mounting of the apparatus with asparking device p, Fig. 1, to act as an automatic protector consistingof two bent metallic rods. By means of a screw these two rods can beapproached together to such a degree that the operating of the sparkingdevice will be certain as soon as the potential has reached a limitdangerous to the security of the apparatus.

I claim An apparatus for supporting and cooling statical ozonizerscharacterized by a metallic electrode a suitably insulated by means of abox b, and an exhaust-pipe c for withdrawing the ozonized air, the saidmetallic electrode being supported between two dielectric surfaces: dwhich are covered on the exterior bya conductor e and cooledcontinuously by a spray of water which saturates a layer of porousmateriel f such as felt or any other suitable substances, and e sparkingdevice of which one of the ends is joined to earth and the othereonneeted with the central electrode a,

5 forming a, kind of electrical safety-valve for the Whole apparatus.

In testimony whereof I have hereunto set my heed in the presence of twosubscribing Witnesses.

MARKETS OTTO.
